The Dual-Sliding Fin Lock Assembly provides a simple, cost-effective and secure locking mechanism that engages on the initial opening stroke of a fin of a flying object, using a minimal number of parts that are easy to manufacture. Two sliding locks, each having a protruding step, engage with two fin lugs each of which has a corresponding notch. When a step and a notch fit together, they form a contact plane which may be straight horizontal or inclined to ensure robust locking operation without the need for extremely tight tolerances on the individual parts or on the assembly. Since the sliding locks do not rotate around the pin that holds the fin lugs, they engage the fin lugs to arrest the rotation of the fin and retain it securely in the deployed position for the duration of the object's flight, guiding the object more accurately toward its destination.

We claim: 1. A multi-sliding fin lock assembly for locking a deployed fin in place on a flying object so as to render stability to the flight of the object and enable the object to reach its pre-selected destination more accurately, said lock assembly comprising: a plurality of object lugs, said object lugs each having a hole therethrough and being fixedly attached to the outer surface of said object while being separated by a given distance from each other; a fin; a plurality of sliding locks, said locks each having a hole therethrough and a protruding step, said sliding locks being positioned between said object lugs; a plurality of fin lugs attached to said fin, said fin lugs each having a hole therethrough and a notch, said step and notch allowing said sliding lock and said fin lug to fit together, each fin lug being sandwiched between one object lug and one sliding lock; a pin passing through said holes of said object lugs, fin lugs and sliding locks, said pin thereby securing said fin to said object; and a means to maintain said fin firmly in the deployed position for the duration of the flight of the object. 2. A multi-sliding fin lock assembly as set forth in claim 1, wherein said maintaining means comprises a spring compressed between said sliding locks, said spring surrounding said pin. 3. A multi-sliding fin lock assembly as set forth in claim 2, wherein said sliding locks are non-rotatably positioned on said object so as to allow said step on a said sliding lock and said notch on a said fin lug to fit together to form a tight contact plane upon said fin's full deployment. 4. A multi-sliding fin lock assembly as set forth in claim 3, wherein the diameter of said holes through said fin lugs are sufficiently larger than the diameter of said pin so as to allow said fin lugs to rotate freely about said pin. 5. A multi-sliding fin lock assembly as set forth in claim 4, wherein said contact plane is horizontal. 6. A multi-sliding fin lock assembly as set forth in claim 4, wherein said contact plane is slightly inclined to enhance the lock between said sliding lock and fin lug. 7. A dual-sliding fin lock assembly for locking a deployed fin in place on a flying object so as to impart stability to the flight of the object and enable the object to reach its pre-selected destination more accurately, said assembly comprising: a first and a second object lug, said object lugs each having a hole therethrough and being fixedly attached to the outer surface of said object, said first and second object lugs being separated by a given distance from each other; a fin; a first and a second sliding lock, said locks each having a hole therethrough and a protruding step, said sliding locks being fixedly positioned between said object lugs; a first and a second fin lug attached to said fin, said fin lugs each having a hole therethrough and a notch, said step and notch allowing said sliding lock and said fin lug to fit together, said first fin lug being sandwiched between said first object lug and said first sliding lock while said second fin lug is sandwiched between said second object lug and said second sliding lock; a pin passing through said holes of said object lugs, fin lugs and sliding locks, said pin thereby securing said fin onto said object; and a means to maintain said fin firmly in the deployed position for the duration of the flight of the object. 8. A dual-sliding fin lock assembly as set forth in claim 7, wherein said maintaining means comprises a spring compressed between said sliding locks, said spring surrounding said pin. 9. A dual-sliding fin lock assembly as set forth in claim 8, wherein said holes through said fin lugs are sufficiently larger than the diameter of said pin so as to allow said fin lugs to rotate freely about said pin until said fin reaches full deployment. 10. A dual-sliding fin lock assembly as set forth in claim 9, wherein said sliding locks are positioned on said object to allow said step on said first sliding lock and said notch on said first fin lug to fit together to form a first tight contact plane upon said fin's full deployment. 11. A dual-sliding fin lock assembly as set forth in claim 10, wherein said sliding locks are positioned on said object to allow said step on said second sliding lock and said notch on said second fin lug to fit together to form a second tight contact plane upon said fin's full deployment. 12. A multi-sliding fin lock assembly as set forth in claim 11, wherein said contact planes are horizontal. 13. A multi-sliding fin lock assembly as set forth in claim 11, wherein said contact planes are slightly inclined to enhance the lock between said sliding locks and fin lugs.
